“…Previously, we found that following prednisolone (or unspecified corticosteroid) exposure, average pregnancy duration in the majority of randomized controlled trial (RCT), case-control, cohort and case-series studies (where reported) was usually term, at ≥37 weeks [ 43 , 51 , 84 , 85 , 88 , 92 , 94 , 96 , 101 , 102 , 104 , 105 ]. Other studies reporting ≤37-week delivery were confounded by factors such as maternal disease and concomitant medications [ 46 , 57 , 59 , 60 , 86 , 87 , 99 , 106 , 113 , 117 , 163 , 165 ]. Birth weights followed a similar pattern and were affected by preterm deliveries and confounding factors, as described above.…”
